The invention relates to a safety agglutination glass structure, comprising two glass substrates and a heat insulating adhesive membrane. The heat insulating adhesive membrane constituted of heat insulating particles and a colloid material is disposed between the two glass substrates. Therefore, the two glass substrates can combine together by heating and pressurizing for the purpose of simplifying processing procedures, reducing the costs and preventing distortion.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a safety agglutination glass structurewhich can avoid the problems of bubbles formation and distortion duringthe bonding process and can effectively simplify the processingprocedure.

2. Description of Related Art

As to the composition and process of the conventional agglutinationglass, there are two forms as described below. First, as shown in FIG.3, the conventional agglutination glass comprises two glass substrates(51), a heat insulating membrane (52), and two glue membranes (53),wherein the heat insulating membrane (52) is disposed between the twoglass substrates (51) forming two spaces and the two glue membrane (53)are further disposed within the two spaces respectively. Inmanufacturing the conventional agglutination glass, the glue membrane(53) is disposed on a cleaned glass substrate (51), and the heatinsulating membrane (52) is disposed on the glue membrane (53). Then theother glue membrane (53) is further placed on the heat insulatingmembrane (52) and finally is covered with the other glass substrate(51). The glue membrane (53) and the heat insulating membrane (52) canbe combined by heating and pressurizing. However, this process willcauses lots of bubbles under the glue membrane (53) when air getstrapped between membranes, and the heat insulating membrane (52) is alsoprone to shrinkage and distortion leading to the high defect probabilityof the finished goods. Therefore, many disadvantages still exist in thestructure i.e. unstable product quality (bubble formation anddistortion) and waste caused by complicacy in manufacturing procedure.

Also, as shown in FIG. 4, the conventional agglutination glass primarilycomprises two glass substrates (61), a plating layer (62), and a gluemembrane (63). Even though this structure and its laminating procedurecan solve the aforementioned problem of distortion, one of the glasssubstrates (61) requires to be pre-plated with a metal plating layer(62). The other glass substrate (61) is further disposed with a gluemembrane (63) and then combined with the glass substrate (61) coveredwith the plating layer (62) by heating and pressurizing. Accordingly,this conventional agglutination glass structure also has somedisadvantages i.e. complicated process and waste of cost caused bynecessary use of prior plating procedure and the complex manufacturingprocedure.
